Hi all,
How do I return pictures along with my search results? For example, I have a shoe database and for the results I would like one column to hold a picture of the shoe (the other columns hold Brand, Name, Price, etc) The way I am looking at implementing this is by referencing the image and retrieving it from the server. I'm a bit lost on how to do this though. Any help?
Thanks in advance,
Nick
For example, the table below, has a foreign key (ManagerId) that points to EmployeeId (primary key) of the same table.
-------Employees table--------
EmployeeID . . . . . . . . . . int
Name . . . . . . . . . . . nvarchar(50)
ManagerID . . . . . . . . . . . int
If someone gave you an ID of a manager, and asked you to get him all employee names who directly or indirectly report to this manager.
How can that be achieved?
I am using the 3-tiered architecture design (presentation, business laws, and data acess layers). I am stuck on how to send the image the user selects in the upload file control to the BLL and then to the DAL because the DAL does all the inserts into the database. I would like to be able to check the file type in the BLL to make sure the file being uploaded is indeed a picture. Is there a way I can send the location of the file to the BLL, check the filetype, then upload the file and have the DAL insert the image into the database? I have seen examples where people use streams to upload the file directly from their presentation layer, but I would like to keep everything seperated in the three classes if possible. I also wasn't sure what variable type the image would be in the function in the BLL that receive the image from the PL. If there are any examples or tips anyone can give me that would be appreciated.

hi all,
i have created a table with image field in it. Now i just want to store a jpeg file in it but not finding any way to do so.
how can i store any image ? what are the steps???????
thanx in advance
Ok, the problem is that , i have a field called "Attach" in sql of type image, when selecting it , the field is getting data of type BYTE(). which am being unable to display them on an Image on the panel.
using the following vb.net code:
'Dim sel2 As String
'Dim myCom As SqlCommand
'Dim conn As New SqlConnection
'Dim drr As SqlDataReader
'Dim image As System.Drawing.Image
'sel2 = "select * from attach where att_desc = '" & DropDownList1.SelectedItem().Text & "' and doc_code = " & w_doc_code & " and subcode = " & w_doc_subcode & " and doc_num= " & w_doc_num & " "
'conn.ConnectionString = ("server=developer01;uid=sa;password=aims;database=DVPSOC;timeout=45")
'myCom = New SqlCommand(sel2, conn)
'conn.Open()
'drr = myCom.ExecuteReader()
'If drr.Read Then
' Me.ImageMap1.ImageUrl = drr.Item("attach")
'End If
'conn.Close()
Am getting an exeption on the following line Me.ImageMap1.ImageUrl = drr.Item("attach")
saying: Conversion from type 'Byte()' to type 'String' is not valid.
knowing that i tried converting using ToString but it's not getting any output then.
thanks for your help.
I have learned lots of informative thing from your forums. I have little problem regarding “Display image from SQL Server on ASP.NET� I have done it and image display on my page from SQL Server. I have cleared you here I have adopt two different methods which are following for displaying picture.
1.Response.BinaryWrite(rd("picture"))
2.image.Save(Response.OutputStream, ImageFormat.Jpeg)
but in both above methods I have faced little problem when image display on my page all other information can not display and I also want to display picture on my specific location on the page. My second question is can use any web control like “Image1� to display image from SQL Server where my pictures are stored.
Hope you will help me.
Thanks and regards

View 2 Replies View RelatedIn my asp.net application I have a local report with an image control in thedetail row of the table and the Value attribute set as="File://" & Fields!FQPhotoFileName.ValueThe first row in the table always shows the wrong image and it's always thesame wrong image. The problem is there even when I change the sort order orthe criteria for the underlying dataset. For example, I ran a small testthat populated the dataset with 2 rows and 2 images. When I sort by anycolumn (e.g. ID) in ascending ascending order the ID=1 row (the 1st row)shows the wrong image and the ID=2 row shows the correct image. When I rerunthe report sorting in descending order the ID=2 row (which is now the 1strow) shows the wrong image and the ID=1 shows the correct image.Any suggestions?

I have inherited a VS 2005 database with a table that has a column of type IMAGE. I need to change the image for one of the rows in the table. I have the new image in a *.PNG file on my C: drive. What is the correct method for inserting this file into the IMAGE column.

I have a SqlDataSource - The select statement
selects the DB row with an ID that equals a querystring value.... So I
know I am only selecting one row..Now I want to create a little
Sub that grabs any field(s) of my choice and then I can assign the
value of it to a textbox on my page or a variable if I need to... Any
idea how I actually reference the fields via the SQLDataSource in a
sub? I see you can reference parameters using..SqlDataSource1.SelectParameters()I was hoping I could use something similar to get the actual DB fields like the below...SqlDataSource1.Select("MyDataBaseField").Value = TextBox.TextCan anyone help please??Thanks
The Background:
From page 1 a search is created and this value is converted to a querystring and given the name "id=" and passed to page 2. Page 2 then does a lookup in the sql 2000 db useing this querystring.
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:ListingDBConnectionString %>"
SelectCommand="SELECT [ID], [CompName], [Package] FROM [CDetails] WHERE ([ID] = @ID)">
<SelectParameters>
<asp:QueryStringParameter Name="ID" QueryStringField="id" Type="Int32" />
</SelectParameters>
</asp:SqlDataSource>
The Problem:
What I then need to do is an IF THEN ELSE statement.
IF [Package in SQL1] = 4 Then
Package 4
IF [Package in SQL1] = 3 Then
Package 3
Only how do I reference the sql value in the if statement.
I have tried
<%IF Eval("Package") = 4 Then %> and with Bind - No good
Hi,
I'm using MS SQL 2005 Express.
CREATE TABLE Folder (
iD int NOT NULL IDENTITY (1, 1) PRIMARY KEY,
folderName varchar(50) NOT NULL,
parentFolderID int NULL
FOREIGN KEY REFERENCES Folder (iD)
)
GO
if I add an ON DELETE CASCADE to the foreign key, then i get an error... which is annoying. If a folder is deleted, then all its sub-folders should also be automatically deleted.
The error is: 'Introducing FOREIGN KEY constraint 'FK__Folder__parentFo__7D78A4E7' on table 'Folder' may cause cycles or multiple cascade paths. Specify ON DELETE NO ACTION or ON UPDATE NO ACTION, or modify other FOREIGN KEY constraints.'
Anyone got any advice?

I'm setting up a trigger that will fire off an email explaining that this entry has been updated, however I need a reference to the updated row so I only send that bit of information off.
Heres my code thus far:
ALTER TRIGGER [dbo].[completeCreation2]
ON [Database_Test].[dbo].[Projects]
AFTER UPDATE
AS
-- SEND EMAIL
EXEC msdb.dbo.sp_send_dbmail
@profile_name = 'Administration',
@recipients = 'email@email.com',
@body = 'A new project has been created view details of the project below:',
@subject = 'Project Created',
@body_format = 'TEXT',
@importance = 'High',
@query = 'Select * FROM updated';
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON;
END
I thought the select From updated would work but it doesn't I need a reference for that line, select * FROM _____.
Thanks
I am trying to run a mobile device with SQL's mobile 3.5.
When I run my application I am given an error that sqlceme35.dll plus several other references cannot be found
When I try referencing them It does not allow me too.
Is there any steps I should take to make referencing allowed?
Hi
This is probably a noob question. In reference to my previous post about OLE DB and variables, I need to copy the whole result set to a table. i tried
Code Block
exec('insert into '+@tableName+' ('+@ColumnNames+') '+@curTableResult)
where @tableName is the table name, @ColumnNames are the column names and @curTableResult is the Result set produced by the Execute SQL statement before. Obviously didnt work.
How do I copy the Result set to a table?
Thanks

Hi there everyone,
A quick question. How do I reference variables (system and user) in SSIS by name instead of by just using a "?". The reason why I'm asking is because I'm trying to log what happens in a package to SQL, and if I cannot reference a variable by name it tries to insert variable values into incorrect fields?
An example of the code I'm trying to use can be found below:
Code Block
UPDATE dbo.History_Control_Table
SET
End_Date = GetDate()
, Result = 'Success'
, Status = NULL
, No_Of_Records_Processed = ? --This is where I want to tell it which variable to use
, Package_Name = ?
, No_Of_Records_Rejected = ?
--etc etc etc
WHERE
Package_Name = ?
AND Task_Name = 'Deals_Fact_Stg'
AND Status = 'Running'
Thanks in advance.

This book 'MS SQL Server 2000 Bible' says the following:
'The foreign key can reference primary keys, unique constraints, or unique indexes of any table'
I've never heard of this before, I thought that the FK always established referential integrity by referencing the PK in the parent table. Does anyone have a further explanation of this?
thx,
Kat
Is there a way to reference textboxes in an SSRS table like one would for cells in Excel? For example, something like =textbox1/textbox2? I am trying to replace a spreadsheet by turning it into an automated report and need to do some horizontal formulas and when I put in the grouped total, it always defaults to averaging percetages from the rows above, which isnt a true summary in my case.

create procedure testit as

I'm quite new to using t-sql, so hopefully the answer to this should be fairly simple... I have the following basic stored procedure:
Quote: CREATE PROCEDURE dbo.SP_Check_Login (
@arg_UserEmail VARCHAR(255),
@arg_UserPassword VARCHAR(255))
AS
BEGIN
SELECT a.userArchived,a.userPasswordDate
FROM app_users a
WHERE a.userEmail = @arg_UserEmail
AND a.userPassword = @arg_UserPassword
END;
GO
What I want to do is some conditional statements on the query results.
i.e:
IF (userArchived = 1)
RETURN "Archived"
ELSE IF (userPasswordDate < dateadd(month,-3,getdate())
RETURN "UpdatePassword"
ELSE
RETURN "OK"
So firstly how to I reference the data returned by the query, and secondly am I on the right track with the conditional code?
Thanks, Mike
Hello,
I have an access database and an SQL database and using data transformation services, i want to update the access database using the SQL data.
Can anyone tell me the syntax for referencing the access database?
Is it something like: [TABLENAME].dbo.FIELDNAME ?
Just to clarify, i have
Microsoft Access Database
Table 1 (UnitHistory)
SQL Database
Table 1 (UnitHistory)
How do i reference these seperately? I want to update the microsoft access database based on the SQL database data.
Eventually i'm trying to update an access database using the data held on my SQL server. Is DTS the best way for me to acomplish this or should i use another method?
Thanks guys

The ROLLBACK TRANSACTION request has no corresponding BEGIN TRANSACTION.
Excuse me if my terminlogy is inaccurate, i'm a .NETer that's new to SQL.
I was wondering if it's possible to reference a column in the WHERE CLAUSE that has been customily defined in the SELECT statement
for example
select employeeID, case when JobCode = 'A' then 'Accountant'
case when JobCode = 'C' then 'Consultant'
case when JobCode = 'B' then 'Biller'
End as JobType
from Employee
where JobType is not null
This does not work, and saids JobType is an invalid column name. Basically, what I want is to display the jobtype of the employee but i also want to only display the employees that are Accountants, consultants and billers.
Is this possible and what would be the best way of doing this?
I do not seem to be about to reference JobType in the WHERE statement.
Is there a way to refer to "current report item" using something like "this" or "me"? For example: I find myself often cutting and copying code to change the format or color of text boxes based on their value thoughout a report, and it seems like it'd be more efficient to write the formatting code once and then call it from each text box.
